[LVL ED] New Question: How to create a door

[Nervly]

Hello again Cruzore/FastHunteR or new helper
Well, my new question is, how do I create a door?
Like, I want to make a mirror a door, so I went to the ModelEditor, opened a door file, and replaced the door with a mirror, and that colored boxes are still there and joints, etc.
But when I go on the LevelEditor and place the Mirror Door, ingame the hand doesn't show up, so I cant open it. :/
How do I make the mirror a door?

"
Open your model in the ModelEditor, go to "User Defined Variables" in Settings (I think), and there should be a drop-down arrow at the top of the new window. Look through there, and use "SwingDoor". "

I did that too, but it didn't work.

Thanks for taking your time to help me
